-LRB- CNN -RRB- -- Clark Dever and Joe Dinardo have always taken things to the extreme .

Joe Dinardo , left , and Clark Dever will be spending only 12 hours in each city before going to their next stop .

So when JetBlue announced a monthlong all-you-can-jet pass for $ 599 , it was as if the airline had practically issued them a challenge .

`` We decided to come up with the most extreme length you could take it and have the most fun without being crazy , '' Dinardo told CNN . `` We 've always pushed each other to be more outrageous , so this is just taking that to another level . ''

Dever and Dinardo , friends since their freshman year of college at SUNY Buffalo , will be crisscrossing the country , spending only 12 hours in each city before heading back to the airport and jetting to their next destination .

The deal allows passengers unlimited travel to all cities JetBlue services from September 8 to October 8 for $ 599 .

Dever , who was recently saving up money to be a professional photographer , quit his job , and Dinardo decided to use all of his accumulated vacation time from his job to take the trip .

They plan to make the most of the deal , hitting at least 29 cities in the 31 days by taking about 49 one-way flights .

They 'll sleep during their flights , take showers in gyms , and have friends work as runners to swap out bags of clothes when they fly into New York 's JFK airport about every three days .

They 've even worked with some companies to obtain sponsorships .

They plan to interview fellow fliers to get the skinny on the best places to go in hopes of taking the `` local 's tour '' of a city as opposed to a generic tourist trip for their Web site twelvehoursinacity.com .

`` What better way to get a snapshot of the United States , '' Dever said . `` To really capture the unique culture of each city , to meet all of the different people . ''

And for them , the price is unbeatable . The way they see it , if each flight cost $ 200 , they 're taking a $ 10,000 trip for only $ 600 .

Which is exactly why the promotion has received such a great deal of buzz , specifically among social networking platforms . JetBlue suspended the deal two days early , saying they were sold out , though the company declined to specify how many people bought them .

Jennifer Milano , who is taking time off from freelance work to take advantage , grabbed a pass right away . She decided that with the buzz on Twitter , she could start organizing a group of fellow all-you-can-jet travelers , calling it the 599club .

She created a site where people are sharing their itineraries in an attempt to either travel together , meet up with Twitter followers in their cities or try to couch surf at other people 's homes . Some may even meet in California to go skydiving together .

Will and Cara Dearman had been planning to move to New York from Austin , Texas , when they heard about the deal . So they decided to pack up their home , bring in the movers and head off for vacation before their big move .

Given JetBlue 's hub structure , many travelers found a slight hiccup : If they were in the Midwest , they might have to travel all the way back to New York to travel to the West Coast .

The couple will be spending a large chunk of their trip in South America and the Caribbean and will be doing video interviews with entrepreneurs around the world for Will Dearman 's Web site , TheStrategyBlog.com .

For Greg Krause , the pass is a chance to raise money for a charity close to his heart , - an elementary school in Zambia that his parents created for orphaned children in a small village two hours from a main road .

Krause plans to go to 24 cities , using about 45 different flights , to have both an enjoyable vacation and hopefully meet people who will donate to the school . He also will be documenting his trip on his Web site , 30daysonjetblue . com .

Though Dever and Dinardo may have the most exhausting schedule , they , like many others , think that if nothing else , the trip will be a true adventure .

`` No matter what happens , there will certainly be a story that comes out of this trip , '' Dever said . `` For us , the biggest concern will be finding a place to shower . We certainly do n't want to be the stinky guys on the plane , especially for that many flights . But either way , its going to be an adventure , a tiring but exciting adventure . ''
